The object of this invention is to provide a compact and conveniently operable implementresembling a hand stamp in that it includesa base or bed and a plunger, adapted to be manually projectedvtoward the bed and automatically retracted therefrom like the plunger of'a hand stamp, the bed being adapted to support aipaperarticle such as a tag or a leaf reinforcing'patches, one at a time, to articles successively placed'on'the bed, the patches surrounding holes in the articles to which they are applied. 1 ..A particular object of the invention is to provide nieansfor connecting a-charge of patches with the'plunger 'in such manner that the patches may be applied successively until the charge is exhausted, the connecting means being removable from the plunger and adapted tobe' provided, when removed, with anothercharge. 7 vi 1 Of 'the accompanying drawings forming a part of this specification, 7 Figurel is :aperspective'view of an impieme'nt embodying the invention, the plunger ing 'retracted. y L a a Figure 2 is a sectional view,showing a fragment of the base, the plunger being retracted. f

is adapted to be manually projected toward the; bed and is normally res tracted by a spring 2l interposed, in this into stance, between a fixed abutment- 22 in the bore of the plunger and a head 23' fixed to the upper end of the plunger, the abutment'22 being fixed tothe guide 20 by-clamping screws 24' engaged with the guide and with opposite sides of the abutment The screws: pass 1 through longitudinal slotsj 180 in opposite 25 designates a cylindrical core whereona form a cylindrical body or chargefrom which the patches'may bedetached or dispensed one at a time. p The core is-preferably a short length 5 of brass tubing of a suitable diameter to permit the patches to slide freely 'on ,to' one of ,its ends' "and toward its delivering-end which is the lower end in Figure 2 Said. delivering end has an enlargement 27 (Figure 10) formed to releasablyengage an endpatch 26 and support the charge in contactwith the: pressing face 19-of the plunger, Said enlargement is preferablyaivery narrow outwardly proj ect ing flange or bur formed onthe end of. the core, and adapted to prevent 1 accidental re: moval from thecore of an end patch bearing on the enlargement, sothat the enlargement dropping from'the core when the latter is in a yerticalposition. The enlargement is also adapted-to permit the removalfrom the core of a patch which has been applied to an article 16, as hereinafter described. The core. 25is slidablelongitudinally in the bore of-the. tubular plunger, so that it may be telescoped therein as indicated by Figure 11, to conform to any decrease in the length charge in contact withthe pressing face of the plunger.

I provide frictional retaining means adapted to releasably maintain the core in any position to which it is slidable in the plunger and permit the removal of the core from the plunger after a charge has been exhausted, so that'the" core may berecharged I embody the preferred frictional retaining means-in a cylindrical plug or slide 29, located loosely in the plunger core between the abutment 22' and an internal stop shoulder 30on-the plunger, and a stud 31xprojecting from the slide and adapted to enter and frictiona lly engage the upper end portion of the core, said end portion being" split bya slot or slots 82,- so that it is adapted to hug the stud.- When the plunger is fully retracted the "slide '29' is rigidly-backed by the abutment-22, as shown by] FigureQ, so that the split end of the core 1 maybe forced upon the stud and frictionally engaged therewith, the slide and stud being supported by the. stop shoulder'30; sothat the co're may be removed from theplunger by i pulling it downward from=the stud. The-alternative frictional 'retaining means shown by Figures1 2- and 1 -3 is provided by a split ring 33 confined" in the plunger bore between stop'shou-lders 34" andadapted to yieldingly embra'cethe core 25, the core being slidable in and removable' fromthe ring 33.

f The bed isprovided with an upward-1y projecting boss 35, formed to enter a l1ole17 in an article16 pla'cedon thebedand located a'linement with'thecore V The implementis prepared for operation bys'tringing patches on the core to form a suitable charge, then engagingthe core as described the plunger While the latter is retracted, one end of the charge being'ma intainediincontact with the pressing face 19 of the plunger; 3A portionof an article 'l 5 surrounding the hole 1*6 is then moistened, and the article is depositedonthe bed with its moistened portion facing upward? The plunger is then manually project-ed until the releasably' confined end 'patch is applied to the moistened portion of: the article, the gummed surfaces of the patches facing down-{ Ward,soithat the applied patch adheres to the article; Theiplnnger is then released andretractedi The adhesion of the appliedpatch to the article, and r the described form of the end enlargement of; the core enables saidpatch tobe'sepa-rated from the core without being detached from the article,the next patch ofthe charge becoming an end patch which is releasably; arrestedby the end enlargement of the core and adapted to be applied to' an article on the bed. 1

As shown by Figure 1'1 ,-t-he core maybe telescoped intothe plunger until the' last patchof the charge is applied:

It'will be seen that the implement-may be retracted.
